ABSTRACT:
Rapid curing, high strength cementitious binder mixtures are provided containing fly ash and an alkali metal or alkaline earth metal silicate binder that has a weight ratio of SiO.sub.2 :M.sub.2 O of about 0.20:1 to about 0.75:1 wherein M is selected from the group consisting of Li, Na, K, 1/2Ca and 1/2Mg. The cementitious binder mixtures can be mixed with aggregates to provide mortar and concrete mixtures. Any of the binder, mortar and concrete mixtures can be cured under elevated temperatures to yield high strength products.
